Q:What kinds of steel pipe are divided into?
According to the weld shape can be divided into longitudinal welded pipe and spiral welded pipeStraight welded pipe: the production process is simple, high production efficiency, low cost, rapid developmentSpiral welded pipe: strength ratio of longitudinal welded pipe is high, with a narrow billet production of large diameter pipe, also can use the blank production of the width of the same diameter of different pipe. But with the same length of straight pipe, weld length of 30~100%, and the production rate is low. Therefore, the smaller diameter pipe most used straight large diameter pipe welding, mostly using spiral welding.Dividedagain general welded pipe, galvanized pipe, blowing pipe, wire tube, pipe metric, roller tube, deep well pump, tube for automobile, transformer tube, welding, welding of thin-walled tube shaped tube and spiral welded pipe.General general pipe: pipe used for conveying the low-pressure fluid. Q195A, Q215A and Q235A made of steel. Also can be used for easy welding of mild steel. The other pipe to conduct water pressure, bending and flattening test, have certain requirements on the surface quality, usually the delivery length is 4-10m, often requires a fixed length (or size) of delivery. The specifications of welded pipe with nominal diameter (mm or inches) nominal diameter and different pipe wall thickness, according to the provisions of general steel and thicker steel two, steel pipe end is divided according to form of threaded and non threaded two.
Q:How much is the tube?
The theoretical weight calculation formula of ordinary carbon steel tube is:The weight of each meter is kg/m= (outer diameter mm-, wall thickness mm) * wall thickness mm*0.02466For example: inventory 20# pipe diameter of 108*4.5 weight per meter:Kg/m= (108-4.5) *4.5*0.02466=11.485In accordance with the diameter of 108*4.5 steel pipe market price is 4500 yuan / ton as an example, we can know the diameter of 108*4.5 steel pipe per meter price: 11.485*4.5=51.68 yuan.
Q:Seamed steel pipe seamless steel pipe, carbon steel pipe, galvanized pipe, four how to distinguish between
Major use differentiation:1, seamed tube can withstand the maximum operating pressure is generally less than 20 kg, which is the most secure use. It is generally used in water, gas, compressed air and other low-pressure fluid;2 seamless tube can withstand ultra-high pressure, of course, its wall thickness will also increase, which needs to be designed according to pressure requirements. It is generally used in high-pressure oil pipes, boiler tubes and other high temperature and high pressure equipment. There are also seamless tubes for structural purposes, depending on the design requirements.3, there are some seamed steel pipe seamless treatment tube, it is the weld annealing treatment, eliminate the residual stress of the weld, the weld and base material, the pressure range of basic and seamless pipe is. May also consider the use of.4, of course, the market also has some use overall heating after drawing steel pipe joints or mandrel rolling seamless steel pipe, mainly in small size, only in the shape of this kind of pipe belongs to the seamless tube, it is not very good
Q:What's the difference between hot dip galvanizing and cold galvanizing? Which kind of galvanizing method is good?
Cold galvanizing refers to the zinc plating, the coating is thinner, corrosion resistance is slightly worse, variable color. Environmental pollution.Hot dip galvanized by molten zinc ingots, the coating thickness can be adjusted, good corrosion resistance, and subsequent passivation, can be used for outdoor rust, long service life, some up to 20 years.
Q:What is ND steel pipe?
ND steel also has the ability to resist chloride ion corrosion. ND steel pipe, the main reference indicators (70 degrees Celsius, 50%H2SO4 solution immersion 24 hours), and carbon steel, Japan imported similar steel, stainless steel corrosion resistance compared to higher than these steel grades. Products by domestic refineries and manufacturing units after the use of widely acclaimed, and achieved good results.
Q:How much is 4 inches steel tube MM?
Seamless root weight per meter: 1 mm (diameter - thickness) * wall thickness of *0.02466*1 meters is? Normal KG/M pipe length 8-11rice
Q:Is hot dipped plastic pipe steel?
The characteristics of hot dipped plastic pipe are:1., hot dipped plastic pipe superior anti-static performance: through the formula to add antistatic agent, so that its internal and external surface resistance value reached and exceeded the national industry standards.2., such as the use of plastic raw materials, add flame retardants. The flame retardant performance index conforms to the national standard, and the steel plastic composite structure has better flame retardance than the pure plastic pipe material, and is suitable for underground inflammable, explosive and other places.3. hot dip coating steel strong adhesion: steel surface after special treatment, curing, coating adhesion is greater than or equal to 30N/10mm.4., dense internal and external resin layer: coating thickness of more than 0.5 mm, no pinholes, with excellent corrosion resistance.The mechanical properties of plastic steel pipe superior 5. hot dip: can withstand the harsh conditions of use: coating steel has good toughness, high mechanical strength, impact bending and other foreign influence, has a strong bearing capacity, has better performance than other mine plastic pipes.6. hot dip steel corrosion and fouling, the fluid resistance is small: corrosion and fouling, especially suitable for the underground conveying high sulfur water and transport of calcium and magnesium plasma water, save the maintenance cost, service life is much higher than that of the other pipe, high economic benefit.7. self lubrication: smooth wall, no fouling, small transmission resistance, under the same conditions, can improve the transport capacity of 30%.8. convenient and reliable connectionThe utility model completely overcomes the defects of the difficult connection of the pure plastic mining materials, and can be connected with the underground steel pipe and the valve by using flanges, fast couplings, etc., and has strong interchangeability.
Q:What's the difference between seamless steel pipe and welded pipe?
Welded steel pipe, also known as welded pipe, is made of steel or strip after the formation of welding welded steel pipe, usually 6 meters in length. Welded steel pipe production technology is simple, high production efficiency, varieties and specifications, equipment investment is less, but the general strength is lower than seamless steel pipe.
Q:What is the buckling type thin-wall steel pipe? What is a tight set of thin-walled steel tubes? What's the difference between the two?
The nut body and the junction box are connected at one end by adopting metric fine tooth thread, and the pipe is connected with the pipe, and one end is the same as the straight pipe joint (direct). Withhold the box joint points inside and outside teeth two. The diameter of straight pipe joint is divided into 16mm, 20mm, 25mm, 32mm, 40mm, 50mm.
Q:The difference between carbon and welded steel tubes
Seamless steel pipe is made of Steel No. 10-20. It is of high quality carbon structural steelWelded steel pipe is usually welded by Q235 steel plate
